GE Silicone II* Concrete Caulk



30-MINUTE RAIN-READY

Caulk has to have enough time to build adhesion to the surface and cure or dry adequately so it won't wash away when exposed to water. That means if rain is in the forecast, homeowners and pros typically will have to delay or cancel a project when using most caulks. If not, the rain might wash the caulk away and the job will have to be redone. Silicone caulk, such as GE Silicone II Concrete caulk, develops strength and adhesion quickly so it can be exposed to water in as little as 30 minutes. Some caulk requires up to 24 hours or longer before it can be exposed to water. For homeowners trying to squeeze home maintenance projects into the weekend or pros who are looking to move to the next job, GE Silicone II caulk can decrease the waiting time, helping increase convenience, speed, and efficiency.

SUN-/FREEZE-PROOF

The outside of a home is exposed to harsh outdoor elements throughout the year. Extreme heat, the sun's UV rays, and freezing temperatures can cause acrylic caulk to lose its flexibility and degrade. The permanent flexibility of GE Silicone II caulk keeps it from breaking down so it can protect a home over time. Degraded acrylic caulk can crack and crumble over time, leaving gaps for air and water to seep through. Those leaks can lead to water damage, mold growth, and higher energy bills.

100% silicone

WHY 100 PERCENT SILICONE?

Unlike most non-silicone caulks (water-based, acrylic, siliconized acrylic and latex), 100% silicone is permanently:
  • Waterproof—non-silicones can break down in water over time.
  • Flexible—non-silicones can become less flexible and can even freeze at low temperatures, making them more likely to crack.
  • Shrink-proof—non-silicones can shrink as the caulk dries, which can cause cracks over time.
  • Crack-proof—non-silicones can harden, crack and crumble over time when exposed to extreme heat and the sun's UV rays.

Don't Waste Time and Energy

Not all caulk is the same. Because silicone is permanently waterproof, flexible, and shrink-/crack-proof, unlike most non-silicone caulks, it won't leave gaps or cracks for air and water to seep through over time. Those leaks can lead to water damage, mold growth, and higher energy bills—all of which can translate into your lost time (when you have to do the job again), lost energy, and lost money.
